Registered outcomes1
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Percentage valve expansion measured by fluoroscopy | immediately after TAVI procedure | Expansion of the implanted transcatheter heart valve, expressed as a percentage of the manufacturer's nominal cross-sectional area for the implanted valve size. Valve diameters are measured at the inflow, midframe, and outflow levels in three-cusp and cusp-overlap fluoroscopic views. At each level, the diameters from the two views are averaged, and the cross-sectional area is calculated using the circular area formula. Fluoroscopic images are evaluated by independent imaging core laboratory assessors blinded to treatment assignment and clinical outcomes. |
